How fast do you drive with camper on? .

You've probably passed me at one time or another. :B

I've had campers towing horses fly past me several times.

And I totally agree with the fuel cost. I drive where I'm comfortable and the cost of fuel is what it is.

I drive 65-70 most of the time on interstate highways but have comfortively driven at the same speeds on good gravel roads in AK and the Yukon.

Depends on the speed limit and the condition of the road.

Interstate hwy, 65ish, unless the speed limit is lower than 65.

other roads, I follow the speed limit or go slower when needed due to the condition of the road, traffic conditions, etc.

There are trips I take only for the purpose of getting the horse from one competition to another such as San Francisco Bay are to Lexington Kentucky. Thats 2500 miles. The name of the game is to minimize the hours that the horse spends traveling so that we can maximize the total number of rest days before the competition to let the horse recover and get used to the new surroundings. Thats a 4 day drive followed by 5 recovery days and four days of competition then 4 days back home. After that the horse gets at least a week of nothing but hand walking.

I have driven as fast as 80 mph to get past a long line of tractor trailer rigs but otherwise keep my speed well below 70 mph. With a camper the truck is having to overcome air drag with increases exponentially with speed. At 80 MPH the air drag is 300% greater than at 40 mph.

With my own diesel pickup and a cabover camper the truck would average 13 mpg on the highway at 62-65 mph. With a 10 mph headwind I was in effect driving at 72 mph and the miles per gallon would decrease by 10%. If I was driving at 70 mph with a 10 mph headwind the truck would drop to 8-9 mpg and I was consuming 20% more diesel fuel and would need to make a fuel stop much sooner.

Not to drift off topic but gas mileage has never been a concern as to how fast I drive.

I drive at speeds that I am comfortable at and the gas mileage is what it is.

It's not the economy so much as the range that bothers me. Increasing the range = work.

Drive your RV. Within short order, you will develop a feel for how fast you can drive under certain conditions.

If you can't figure it out quickly, you probably shouldn't be driving an RV.

I am comfortable at 60 to 65 no matter what everyone else is doing. Wet weather a little less.

I usually drive the speed limit and that's up to 80 in parts of the desert west.

The Continental 19.5’s that come on the F450 pickups carry an “N” (87mph) speed index rating, and the truck is electronically limited to 85 mph max. Not just under cruise control, but at all times.
